摘　　要：本文结合国土资源部数据中心现状,分析研究了实现同城灾备的技术方案,即同步传输方案和异步传输方案,以及这些技术方案的技术实现层面:存储层、主机层和数据库层。在此基础上,本文进一步分析了两种方案的技术框架、设备组成和技术特点,并对两种方案在数据安全保障、对生产系统影响、传输距离和带宽要求和应用场景等方面进行了对比,为今后同城灾备中心建设提供了思路。Based on the current status of data center of ministry of land and resources （MLR） , this paper discussed two technique schemes of data disaster backup center construction, i.e., synchronous transfer technique and asynchronous transfer technique. Also, the two schemes＇ implementation was discussed through storage layer, server layer and database system layer. Furthermore, this paper analyzed the framework, hardware equipment and technique peculiarities of the two schemes. Moreover, this paper compared the following aspects of the two schemes： data security, influence on application system, transfer distance and bandwidth, application situation. The above work could provide some tips for data disaster backup center construction in the same city.
